"They are promoters of property investment schemes but they do need to comply with various aspects of Australian Consumer Law, and one of those areas is in relation to the 10-day cooling-off period that relates to unsolicited selling.

"Where a trader is involved in selling products other than their normal place of business, then these provisions apply."

Mr Stowe says property spruikers must inform consumers of their rights and must not make false or misleading representations to people who attend the seminars.

"I think it's the hard sell that accompanies, the initial information that's provided to the public about investment in property," Mr Stowe said.

"People going along, thinking they're going to find out some techniques to get involved in the market who unwittingly find themselves under pressure signing up for very expensive training programs and other products.

"It's that hard sell that a lot of consumers may be unaware of."

Well-known spruiker Rick Otton has made an enforceable undertaking not to operate his seminars in Western Australia after concerns were raised in that state.

State and territory ministers are due to discuss the issue of property spruikers next month.

Promoters can be liable for civil and criminal penalties of $1.1 million for a corporation and $220,000 for an individual if they breach Australian Consumer Law.
